MAX202CD RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The MAX202CD is a 2/2 full-duplex RS232 transceiver in 16-SOIC surface mount packaging, manufactured by Texas Instruments. This interface IC operates at 4.5V to 5.5V supply voltage with a data rate of 120 Kbps and receiver hysteresis of 500 mV. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute parts must maintain identical electrical specifications and mechanical compatibility while offering active product status where available.

Substitute Part Grouping Explanation

Substitution of the MAX202CD is determined by strict equivalence across the following critical parameters: RS232 protocol compliance, 2/2 driver/receiver configuration, full-duplex operation, 500 mV receiver hysteresis, 120 Kbps data rate, 4.5V to 5.5V supply voltage range, 16-SOIC package geometry, and surface mount mounting type. Parts are grouped into categories based on product status and manufacturer designation. MFR Recommended substitutes maintain identical specifications with active product status. Parametric Equivalents match all electrical and mechanical parameters but may have different product status. Direct substitutes are pin-compatible alternatives from different manufacturers. Upgrade parts exceed minimum specifications in operating temperature range or data rate while maintaining full backward compatibility.

Engineering Selection Recommendations

For applications requiring direct replacement of the MAX202CD with active product status and identical operating temperature range, MAX202ECSE+T and MAX232ECSE+T are primary selections from Analog Devices Inc./Maxim Integrated. Both parts maintain 0°C to 70°C operating temperature specification and are available in Cut Tape packaging with substantial inventory levels.

For applications tolerating extended operating temperature range (-40°C to 85°C), MAX202IDR from Texas Instruments provides MFR Recommended status with active product availability. MAX202EESE+T and MAX232EESE+ from Analog Devices Inc./Maxim Integrated offer the same extended temperature range with higher inventory availability.

For applications requiring enhanced data rate performance, HIN202EIBNZ and HIN202EIBNZ-T from Renesas Electronics Corporation provide 230 Kbps capability with -40°C to 85°C operating range and active product status. These parts maintain full electrical and mechanical compatibility while exceeding minimum data rate specification.

All substitute parts maintain ROHS3 compliance, MSL rating compatibility, and identical 16-SOIC package geometry. Selection should prioritize active product status and packaging format (Tube or Cut Tape) based on procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can MAX202IDR replace MAX202CD in existing designs? A: Yes. MAX202IDR maintains identical electrical specifications and 16-SOIC package geometry. The primary difference is extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) and active product status, making it suitable for direct substitution.

Q: What is the difference between MAX202ECSE+T and MAX232ECSE+T? A: Both parts are functionally equivalent RS232 transceivers with identical electrical specifications and operating temperature range. The difference lies in the base product number designation (MAX202 versus MAX232) and internal die revision. Both are pin-compatible and interchangeable for the MAX202CD application.

Q: Are HIN202EIBNZ parts compatible with MAX202CD designs? A: Yes, with the following considerations: HIN202EIBNZ maintains identical electrical specifications and 16-SOIC package geometry. The enhanced data rate (230 Kbps versus 120 Kbps) and extended operating temperature range (-40°C to 85°C) provide performance headroom. Full backward compatibility is maintained for applications operating at 120 Kbps.

Q: What packaging options are available for substitute parts? A: Substitute parts are available in two packaging formats: Tube and Cut Tape (CT) & Digi-Reel®. Tube packaging is suitable for manual assembly and lower-volume applications. Cut Tape packaging is optimized for automated pick-and-place assembly and higher-volume production. Selection depends on assembly process requirements.

Q: Do all substitute parts meet RoHS3 compliance? A: Yes. All listed substitute parts maintain ROHS3 Compliant status, ensuring compatibility with environmental and regulatory requirements identical to the original MAX202CD specification.

Q: What is the significance of MSL rating differences? A: The MAX202CD and most substitute parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations for storage and handling. HIN202EIBNZ parts carry MSL 2 (1 Year) rating, requiring standard moisture control during storage but maintaining full functionality under normal handling conditions.
